Determining the optimum thickness for high harmonic generation from nanoscale thin films: an ab initio computational study
Shunsuke Yamada, Kazuhiro Yabana
We theoretically investigate high harmonic generation (HHG) from silicon thin films with thicknesses from a few atomic layers to a few hundreds of nanometers, to determine the most…

Symmetry properties of attosecond transient absorption spectroscopy in crystalline dielectrics
Shunsuke Yamada, Kazuhiro Yabana
We theoretically investigate a relation between the crystalline symmetry and the transient modulation of optical properties of crystalline dielectrics in pump-probe measurements us…
